Transmission Control Modules & Units

Transmission control modules (for example, a 4L60E transmission control module) manage shift firmness and shift points on electronically controlled transmissions. Aftermarket options allow you to make changes to transmission shifting behavior for improved performance. Because control modules are complex, they can be expensive to purchase.

When choosing an aftermarket transmission control module, the first step is to research and confirm which model of transmission you have. Once this has been established, the next step is finding all transmission control module options that match. From here, choose the one that meets your budget and application needs.

Most transmission control modules range in price between $300 and $2,000, depending on the transmission model, options, and brand.
